Dry concrete Lakka S 100 1000kg

Frost-resistant basic concrete for repairs to concrete structures and small concrete castings such as foundations, footings, floors and stairs. The working life of the mass after adding water is approximately 1–2 hours.

Dry concrete S 100 is a weather-resistant "basic concrete" that can be used for repairs to concrete structures and for pouring foundations, footings, floors and stairs.

The pot life of the mass after adding water is approximately 1–2 hours. The hardening time depends on the layer thickness, air and substrate temperature and ventilation. The smooth concrete surface can later be painted with alkali-resistant paint.

The product is CE marked. The product information has been certified for the Nordic Ecolabel in accordance with the criteria versions 3 and 4 for new buildings.

A bag (25 kg) of dry concrete is mixed with approximately 2–2.5 liters of water using a concrete mixer or drill beater. The powder is added to clean room-temperature water in a clean mixing container. When the entire amount of powder has been mixed with the water, continue mixing for approximately 2–3 minutes until the mass is smooth and without lumps.

The working time of the mass mixed with water is approximately 1–2 hours. After the concrete casting has hardened, it is re-moistened and the casting is covered with plastic wrap for 3–5 days to prevent the surface from drying out too quickly.
